* Be it knownthat I, CARL? OrroiCnnlsrian, PACK, a citizen of the UnitedStates, residing at Highl nd Park, in the. eournty'ofv Mid-- dlcsex andState of New Jersey, have ilk. vented certain new and useful hnprotemments in Rolls, ofwhich the followiugis a,

specification. 4

to provide at the center of the rollan" improved ball bearing havingimprouedmeans for adjusting the roll sections on; the arbor, and therebyadjusting the bearingte take up wear of the balls or the runways,- andproide impr ved, means. between the ro 1se from entering the bearing,and will confine the lubricant within the bearing to prevent its contactwith the thread. I

A further Object is to provide a roll of the character stated which willrun true under any pressure, and which will reduce friction to a minimumso as to efliciently perform the functions for which it is intended.

With these and other objects in View, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out intheclaims.

In the accompanying drawings: Figure 1 is a view in side elevationillustrating my improvements. Fig. 2 is a view in cross section on theline 2-2 of Fig. 1. Fig. 3 is a view partly in longitudinal section andpartly in elevation, and Fig. 4 is a perspective view of one of the cups14. 1 and 2 represent roll sections which are illustrated as havingmilledsurfaces, but may be otherwise formed to frictionally engage thethread against whidh they bear.

The sections 1 and 2 are provided in their inner ends with longitudinalcylindrical sockets 3 and 4 respectively, and at the inner end of thesocket 3 in section 1, a screwthreaded pocket 5 is provided to receive ascrew-threaded lug 6 on the end of an arbor; 7 for a purpose which willbe hereinafter explained.

The arbor 7 is of a diameter to snugly fit the sockets 3 and'vl, and isprovided with a' longitudinal groove 8 which performs the Sgecificationof :Letters Patent. 498mm?! med-warm ng amm Patented July 2i, tend;

My invention relates toimprovements in I rolls, andmore particularly toan, ianpig atecl,' toproll for spinning and Weparatorycotton; machinery,.the object of theinvention being Btztdwgen the roll seitgons 1 and 25 nd sapor q-turn enex 137: is M eda l au, l iph. consists of a caslng 10 aying an annulargroove 1,1,to e a F m le nve e emember d 1 common with devices of thiskind The casing 10- has cupped ends am e mann r mdrical the cupped endsof the casing and provide eth r tea s for heha l tions and ball bearingfor preventing, the: lg 2* passage of cotton or other foreign matterinto the casing and adjust the pressure against the halls. Thisadjustment is accompllshed by holding section 2 and turning section 1,which owing to the screw-' threaded lug 6 in the ocket 5, will adjustthe section 1 toward t e section 2, thereby pressin both cones 13 towardeach other and tig tening the ball bearing. Cups 14 are located betweenthe sections and 2, and the ballbearing, and have central openings 15for the accommodationof the arbor 7. The outer flanged edges 16 of T thecups project over the casing 10 and effectually exclude cotton, dirt,lint, or any other foreign matter from the bearing, and also prevent thepassage of lubricant from the bearing to the outer surface of the roll.

I have provided a lubricant opening 17 in the casing 10, through whichlubricant may be supplied to the hearing, but a bearing of this kindrequires but a very small quantit of lubricant as the roll runs freelyon its ba 1 bearings.

It will be noted that with my improvements the bearing can be adjustedwithout dismantling any part of the roll. In other words, the screw 9 ofsection 1- can be 1003- ened, and then section 1 turned, and after theproper adjustment of the bearing is had,

the screw 9 can be returned to place.

Various slight'changes might be made in the general form and arrangementof-parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:

1. A roll of the character described, comprising two sections havinglongitudinal cylindrical sockets in their adjacentends, a cylindricalarbor snugly fitting the said recesses, jam screws in the sectionsengaging the arbor, a bearing located between the sections and aroundthe arbor, said bearing comprising an outer casing having pockets in itsopposite ends, cones fitting the arbor and located in the pockets, ballsbetween the cones and the inner ends of the pockets, and cups locatedbetween the sections and the cones and having flanges at their outeredges overlapping the casing, substantially as described.

2. A roll of the character described, comprising two sections havinglongitudinal cylindrical sockets in their adjacent ends, one member atthe inner end of its socket havin a screw-threaded pocket, a cylindricalar or snugly fitting the said recesses and having a screw-threaded lugat one end engaging the threads in the pocket, jam screws in thesections engaging the arbor, a bearing located between the sections andaround the arbor, said bearing comprising anouter casing having pocketsin its opposite ends, cones fitting the arbor and located in thepockets, balls between the cones and the inner ends of the pockets, saidcones adjustable in the pockets by the turning of one roll section toadjust the same on the threaded lug, and cups located between thesections and the cones and having flange-rat their outer edgesoverlapping the casing, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
